Operation mode of channel p
100B: One-count mode
Start trigger during operation
1: Trigger input is valid.
Selection of TImp pin input edge
00B: Sets 00B because these are not used.
Start trigger selection
100B: Selects INTTMmn of master channel.
Setting of MASTERmn bit (channels 4, 6)
0: Slave channel.
Setting of SPLITmn bit (channels 1, 3)
0: 16-bit timer mode.
Count clock selection
0: Selects operation clock (f
MCK
).
Operation clock (f
MCK
) selection
00B: Selects CKm0 as operation clock of channel p.
10B: Selects CKm1 as operation clock of channel p.
* Make the same setting as master channel.
(b) Timer output register m (TOm)
Bit p
TOm
TOmp
1/0
0: Outputs 0 from TOmp.
1: Outputs 1 from TOmp.
(c) Timer output enable register m (TOEm)
Bit p
TOEm
TOEmp
1/0
0: Stops the TOmp output operation by counting operation.
1: Enables the TOmp output operation by counting operation.
(d) Timer output level register m (TOLm)
Bit p
TOLm
TOLmp
1/0
0: Positive logic output (active-high)
1: Negative logic output (active-low)
(e) Timer output mode register m (TOMm)
Bit p
TOMm
TOMmp
1
1: Sets the slave channel output mode.
Note TMRm4, TMRm6: MASTERmn bit
TMRm1, TMRm3: SPLITmp bit
TMRm5, TMRm7: Fixed to 0
Remark m: Unit number (m = 0), n: Channel number (n = 0, 2, 4, 6)
p: Slave channel number (n < p
≤ 7)
However, timer output pin (TOmp) : p = 1, 3 to 7
